Building AI.
Thinking out loud.

I build enterprise AI—and write about the decisions, trade-offs, and emerging ideas that shape it.

Close to the technology.
Closer to the problem.

I’m a data scientist who likes getting things into the real world. At Marriott International, I lead advanced data science work in personalization and customer decisioning. Before that, I worked on retail analytics at CVS Health and data observability at Precisely.

That experience shapes what I write about: how AI changes customer behavior, what makes a model useful, and how to build systems people can understand and trust.

Through PlainThink, I help teams put AI to work. At AI Safety & Security, I explore the practical questions behind safer agents. I’m also a Forbes Technology Council member and the author of Approach (Almost) Every Business Problem with AI.

Outside the day job, I mentor with SCORE and ADPList.Let’s talk
